I was just sitting down to figure out how to write a device driver, and when I loaded the usbmon module and fired up wireshark the keyboard started behaving. The first few keys were captured with the "modified" keycodes that the usbhid driver doesn't recognize properly, then it seems to have switched into "normal" mode and behaved like a regular usb keyboard. I tried it on two computers with the same result, i.e. sudo modprobe usbmon, sudo wireshark "fixes" the problem for some strange reason. Now if only I could figure out how to trigger the mode switch in a less annoying way that would be great.
